Description
Foreliggende oppfinnelse angår en anordning for sammenkobling av The present invention relates to a device for connecting
to ror hvorav det ene i sammenkoblingsstillingen har en del som ligger utenpå det annet ror, idet hvert av rorene på de sider som vender mot hverandre i sammenkoblingsstillingen har minst et åpent rundtgående spor og idet et koblingselement av elastisk material fastholdes mot aksial forskyvning i sporet på det ene ror og har en fjærende del som rager ut av dette spor og har form av en i det vesentlige stumpkonisk hel ring, hvor den fjærende del er innrettet til å smette inn i sporet i det annet ror, hvor sporet i det annet ror har en stort sett radial flate innrettet til å samvirke med den frems tikkende del for å hindre at rorene trekkes fra hverandre i en two rudders, one of which in the coupling position has a part that lies outside the other rudder, each of the rudders on the sides facing each other in the coupling position having at least one open circumferential groove and a coupling element of elastic material being held against axial displacement in the groove on one rudder and has a springy part which protrudes from this groove and has the form of an essentially frustoconical whole ring, where the springy part is arranged to slip into the groove in the other rudder, where the groove in the second rudder has a generally radial surface arranged to cooperate with the forward ticking portion to prevent the rudders from being pulled apart in a
retning motsatt den hvori de er skjovet sammen, hvor koblingselementet har et fjærende sperre-organ innrettet til å fastholde ringen i aksial retning og som er i form av en stort sett radial krave som når den ene ende av ringen ligger mot en stort sett radial begrensningsvegg i det spor som fastholder koblingselementet strekker seg bort fra ringen på et sted i betydelig avstand, fra den fremstikkende del av ringen og frem mot en motsatt stort sett radial begrensningsvegg i det spor som fastholder koblingselementet. direction opposite to that in which they are pushed together, where the coupling element has a resilient locking member arranged to retain the ring in an axial direction and which is in the form of a generally radial collar which when one end of the ring rests against a generally radial limiting wall in the groove which retains the coupling element extends away from the ring at a place at a considerable distance, from the projecting part of the ring and forward towards an opposite generally radial limiting wall in the groove which retains the coupling element.
Formålet med oppfinnelsen er å skaffe en ny og pålitelig rorkobling som muliggjor at to plastror kan kobles sammen raskt og med enkle håndgrep. The purpose of the invention is to provide a new and reliable rudder coupling which enables two plastic rudders to be connected together quickly and with simple hand movements.
Rorkoblingen i henhold til oppfinnelsen kjennetegnes ved at den del av koblingselementet som rager ut av sporet i det ene ror har en radial endeflate innrettet til å samvirke med den radiale flate i sporet i det annet ror og at sperreorganet, som i likhet med ringen består av et forholdsvis stivt fjærende material, for å sentrere koblingselementet og rorene ligger fjærende mot bunnen i det spor som fastholder koblingselementet og forst i avstand fra det sted hvor det er forenet med ringen. The rudder coupling according to the invention is characterized by the fact that the part of the coupling element that protrudes from the groove in one rudder has a radial end surface arranged to cooperate with the radial surface in the groove in the other rudder and that the locking member, which, like the ring, consists of a relatively stiff springy material, in order to center the coupling element and the rudders lie springily towards the bottom in the groove which holds the coupling element and first at a distance from the place where it is united with the ring.
Koblingen i henhold til oppfinnelsen er også forst og fremst bereg-net på sammenkobling av plastror med moderate dimensjoner, spesielt ror av slikt plastmaterial som vanskelig eller slett ikke kan limes, og er særlig tilpasset etter plastens spesifikke egenskaper, såsom stor tilboyelighet til flytning og stor varmeutvidelseskoeffisient. Koblingen i henhold til oppfinnelsen kan med spesiell fordel anvendes for sammenkobling av polyetenror med en diameter i området fra ca. -g- dm til noen desimeter, selv om den også kan anvendes for sammenkobling av ror med andre dimensjoner.. The coupling according to the invention is also primarily calculated for the connection of plastic rudders with moderate dimensions, especially rudders of such plastic material that cannot be glued with difficulty or at all, and is particularly adapted to the plastic's specific properties, such as great tendency to flow and large coefficient of thermal expansion. The coupling according to the invention can be used with particular advantage for connecting polyethylene pipes with a diameter in the range from approx. -g- dm to a few decimetres, although it can also be used for connecting rudders with other dimensions.
Oppfinnelsen skal nå beskrives nærmere under henvisning til de vedfoyde tegninger som viser et utforelseseksempel, idet ytterligere kjennetegnede trekk vil fremgå herav. Fig. 1 viser et aksialsnitt av en anordning for sammenkobling av to ror i henhold til oppfinnelsen. Fig. 2 viser et tverrsnitt av koblingselementet i henhold til fig. 1 i ubelastet tilstand. The invention will now be described in more detail with reference to the attached drawings which show an exemplary embodiment, as further characteristic features will appear from this. Fig. 1 shows an axial section of a device for connecting two rudders according to the invention. Fig. 2 shows a cross-section of the coupling element according to fig. 1 in unloaded condition.
I fig. 1 betegner 10, henhv. 11 to ror, hvorav bare visse deler In fig. 1 denotes 10, respectively 11 two rudders, of which only certain parts
er vist, og som er koblet sammen ved hjelp av en koblingsanordning i henhold til oppfinnelsen. Roret 10 har en utvidet del eller muffe 12 som ligger utenpå roret 11. De sider av rorene 10 og 11 som vender mot hverandre er utstyrt med åpne spor 13 henhv. l<*>f, idet et koblingselement 15 holdes fast i sport 13 og omfatter en del 16 som i det vesentlige er utformet som en-stumpkonisk hel ring med et fjærende sperreorgan 17, som vil bli beskrevet nærmere i det folgende. Ringen 16 har en radial endeflate 18, som samvir-ker med en radial begrensningsflate 19 i sporet 1<>>+, slik at rorene 10, 11 hindres i å trekkes fra hverandre i en retning motsatt sammenskyvningsinnretningen. Ringen 16 har ved sin basis en indre diameter av muffen 12, slik at den radiale basisflate 20 i sin helhet hviler mot den radiale begrensningsvegg 21 i sporet 13 for å hindre at elementet 15 trekkes aksialt ut av muffen og .for å tillate at roret 11 fores forbi basisflaten 20. is shown, and which are connected together by means of a coupling device according to the invention. The rudder 10 has an extended part or sleeve 12 which lies outside the rudder 11. The sides of the rudders 10 and 11 which face each other are equipped with open grooves 13 or l<*>f, in that a coupling element 15 is held firmly in the slot 13 and comprises a part 16 which is essentially designed as a single frustoconical ring with a springy locking member 17, which will be described in more detail in the following. The ring 16 has a radial end surface 18, which cooperates with a radial limiting surface 19 in the groove 1<>>+, so that the rudders 10, 11 are prevented from being pulled apart in a direction opposite to the pushing device. At its base, the ring 16 has an inner diameter of the sleeve 12, so that the radial base surface 20 rests in its entirety against the radial limiting wall 21 in the groove 13 to prevent the element 15 from being pulled axially out of the sleeve and to allow the rudder 11 is lined past the base surface 20.
Elementet 15 har en såuc,n konisitet at dets minste diameter i ubelastet tilstand er som i det vesentlige lik eller snarere mindre enn diameteren ved den indre ende av sporveggen 19, slik at den del av koblingselementet som stikker ut av sporet 13, smekker inn i sporet lh når rorene 10, 11 skyves sammen. Det fjærende sperre-organ 17, som er innrettet for å samvirke slik med sporet 13 at det sentrerer ringen 16 i forhold til muffen 12 og holder koblingselementet fast i aksial retning, strekker seg bort fra ringen 16 på et sted i vesenHig avstand fra dennes ende 18, frem til en vegg 22 som ligger motsatt veggen 21 i sporet 13. Sprreorganet 17 som er utformet som en ringformet krave, kan med fordel utgå fra ender 20 av ringen 16 slik som vist, og i avstand fra sitt foren-ingssted med ringen 16 ligger det fjærende mot bunnen 23 i sporet 13 hvorved det sentrerer ringen 16 i forhold til muffen 12 uten at det fordres noen storre utforelsespresisjon for sporet 13. The element 15 has such a conicity that its smallest diameter in the unloaded state is essentially equal to or rather smaller than the diameter at the inner end of the groove wall 19, so that the part of the coupling element that protrudes from the groove 13 snaps into the slot lh when the rudders 10, 11 are pushed together. The resilient locking member 17, which is arranged to cooperate with the groove 13 so as to center the ring 16 in relation to the sleeve 12 and hold the coupling element fixed in the axial direction, extends away from the ring 16 at a place at a substantial distance from its end 18, up to a wall 22 which lies opposite the wall 21 in the groove 13. The spreading member 17, which is designed as an annular collar, can advantageously proceed from the ends 20 of the ring 16 as shown, and at a distance from its point of connection with the ring 16, it lies springily against the bottom 23 in the groove 13, whereby it centers the ring 16 in relation to the sleeve 12 without any greater design precision being required for the groove 13.
Det er klart at ringen 16 normalt må kunne oppta betraktelige aksialpåkjenninger og motstå krefter som soker å vrenge den ut av sporet 13. Koblingselementet bor derfor bestå av et forholdsvis hårdt, fjærende material. For alikevel å gjbre det mulig å anbringe koblingselementet 15 i det tilhorehde spor 13 uten van-skeligheter, gjores ringen temmelig tynn, idet dog den radiale tykkelse av ringen 16 bor være storre enn tykkelsen av organet 17. Da organet 17 utgjores av en ringformet krave, forstiver It is clear that the ring 16 must normally be able to absorb considerable axial stresses and resist forces which seek to twist it out of the groove 13. The coupling element must therefore consist of a relatively hard, resilient material. In order to still make it possible to place the coupling element 15 in the corresponding groove 13 without difficulty, the ring is made rather thin, although the radial thickness of the ring 16 must be greater than the thickness of the member 17. Since the member 17 is made up of an annular collar , stiffeners
det ringen 16 på en fordelaktig måte uten å hindre at ringen fjærer inn i sporet 13 ved sammenkobling, av rorene 10, 11. the ring 16 in an advantageous manner without preventing the ring from springing into the groove 13 when connected, of the rudders 10, 11.
Ringen 16 bor i ubelastet tilstand ha en lengde i aksialretningen, som i det minste er litt mindre enn lengden av sporet 13, slik at den kan fjære inn i sporet 13. Den aksiale lengde av. sperreorganet 17 kan imidlertid med fordel være lik eller litt storre enn den aksiale lengde av sporet 13. In the unloaded state, the ring 16 should have a length in the axial direction, which is at least slightly less than the length of the groove 13, so that it can spring into the groove 13. The axial length of. however, the locking member 17 can advantageously be equal to or slightly larger than the axial length of the groove 13.
Fig. 2 viser et tverrsnitt av koblingselementet 15, og viser tyde-lig at sperreorganet 17 er lengere enn ringen 16. Det fremgår også av fig. 1 at lengden av sperreorganet 17 er storre enn den aksiale lengde av sporet 13 slik at sperreorganet også vil ligge mot bunnen 23 i sporet 13. Fig. 2 shows a cross-section of the coupling element 15, and clearly shows that the locking member 17 is longer than the ring 16. It is also clear from fig. 1 that the length of the locking member 17 is greater than the axial length of the groove 13 so that the locking member will also lie against the bottom 23 in the groove 13.
I den indre vegg i muffen 12 er det aksialt og innenfor sporet 13 anordnet et ringformet sete eller spor for en elastisk tetningsring 2h. Alternativt kan tetningsringen, være anordnet i et ringspor som ligger aksialt utenfor sporet 13, eller den kan opptas i det spor 13 som holder koblingselementet 15 fast, idet organet 17 får stotte mot den radiale vegg 22 i sporet 13 gjennom tetningsringen. In the inner wall of the sleeve 12, an annular seat or groove for an elastic sealing ring 2h is arranged axially and within the groove 13. Alternatively, the sealing ring can be arranged in an annular groove which lies axially outside the groove 13, or it can be accommodated in the groove 13 which holds the coupling element 15 firmly, the member 17 being allowed to rest against the radial wall 22 in the groove 13 through the sealing ring.
I en annen utforelse kan tetningsringen være anordnet ved den aksiale indre ende av muffen og hvile mot flaten 25»slik at den klemmes mellom denne flate og endeflaten på roret 10 for i rorenes sammenkoblingsstilling å utove en aksialkraft som soker å skyve rorene fra hverandre. In another embodiment, the sealing ring can be arranged at the axial inner end of the sleeve and rest against the surface 25" so that it is clamped between this surface and the end surface of the rudder 10 in order to exert an axial force which seeks to push the rudders apart in the connection position of the rudders.
Som det vil fremgå av fig. 1 smalner tetningsringen 2h- av mot endene, slik at rorene 10, 11 kan fores sammen uten fare for at den innsatte tetningsring 2h vrenges eller forskyves ut av sitt sete eller spor. Videre kan tetningsringen, slik som vist i den flate som vender bort fra fastholdingssporet, med fordel ha minst et rundtgående spor som tetningsmaterialet vil utfylle i storre eller mindre grad, for eksempel i avhengighet av avstanden mellom de vegger i rorene 10, 11 som vender mot hverandre. As will be seen from fig. 1, the sealing ring 2h tapers off towards the ends, so that the rudders 10, 11 can be lined together without the risk of the inserted sealing ring 2h being twisted or displaced out of its seat or groove. Furthermore, the sealing ring, as shown in the surface facing away from the retaining groove, can advantageously have at least one circumferential groove which the sealing material will fill to a greater or lesser extent, for example depending on the distance between the walls in the rudders 10, 11 which face each other.
Av hensyn til at det spor som opptar koblingselementet 15, normalt har en betraktelig dybde i forhold til tykkelsen av roret 10 kan det med fordel være anordnet en forsterkning på den ene side av roret som er motsatt sporet 13. Der kan f.eks. på utsiden av muffen 12, midt ut for sporet 13, være anordnet et grundt spor, hvor det fores inn en rundtgående forsterkningsring. Således kan rorene 10 og 11 i et praktisk utfdrelseseksempel bestå av polyeten av type HD og koblingselementet av acetalplast, samtidig som en metallring kan være krympet på utsiden av roret 10 rett ut for sporet 13. Due to the fact that the groove that occupies the coupling element 15 normally has a considerable depth in relation to the thickness of the rudder 10, a reinforcement can advantageously be arranged on one side of the rudder which is opposite the groove 13. There, e.g. on the outside of the sleeve 12, in the middle of the groove 13, a shallow groove is arranged, where a circumferential reinforcement ring is inserted. Thus, the rudders 10 and 11 in a practical design example can consist of polyethylene of type HD and the connecting element of acetal plastic, while a metal ring can be crimped on the outside of the rudder 10 just outside the groove 13.
Oppfinnelsen er ikke begrenset til de utforelseseksempler som er beskrevet ovenfor og vist på tegningene, idet mange modifikasjoner er mulige innen oppfinnelsens ramme med hensyn til såvel sporene og koblingselementets utforming som tetningsarrangementet. The invention is not limited to the embodiments described above and shown in the drawings, as many modifications are possible within the framework of the invention with regard to both the grooves and the design of the coupling element as well as the sealing arrangement.
Blant sådanne modifikasjoner kan nevnes at det kan ordnes flere enn ett koblingselement med tilhorende spor av samme type som sporene 13 og lh og at koblingselementet kan holdes fast i et spor i det indre ror. Among such modifications can be mentioned that more than one coupling element can be arranged with corresponding grooves of the same type as the grooves 13 and lh and that the coupling element can be held firmly in a groove in the inner rudder.
